Important updates to the game

If you have a previous version of 'The cave of Alchemy', I sincerely recommend to update the game, as this new update brings fixes to many bugs that I did not notice in my previous tests.

What's new:

• New intriduction screen (can be skipped)
  
• New 'Developed by Polanski' tag in main manu
• Improved Stalactites visual effects when colliding with bodies

Bug fixes:

• Fixed a bug that would always make the player spawn at the beginning of the game when loading
• Fixed a bug that would make the player teleport to the beginning of the game when reaching certain locations
• Fixed a bug that would reset the final battle when the player wins
• Fixed a bug where the cursor would not show in some menus
